Step-by-step explanation:

y=4+x ............................................ (1)

y=x^2+x-12 ............................................ (2)

now equate both (1) and (2)

4+x=x^2+x-12

=x^2=16

x=-4,4

now substitute the values of x ,

when x=-4 , y becomes 0

when x=4 , y becomes 8

so, solution set:

(-4,0) and (4,8)
